Ninja Heater Outdoor Review
Choosing the Right Ninja Outdoor Heater
Heat Output (BTUs)
The British Thermal Unit (BTU) rating is a crucial factor when selecting an outdoor heater. Higher BTUs mean more heat. Ninja Fireside360 heaters offer 80,000 BTUs combined, which is substantial for most patios and outdoor areas. Consider the size of your space – a smaller patio might not require the full 80,000 BTUs, while a larger area will benefit from it. If you live in an area with extremely cold winters, a higher BTU output is essential for effective heating. Conversely, for mild evenings, you might prefer a model with adjustable heat settings to avoid overheating.
Operating Modes & Versatility
Ninja heaters stand out with their multiple operating modes. The availability of flame-only, heat-only, and combined flame & heat modes provides exceptional versatility. Flame-only mode creates ambiance without adding heat, perfect for decorative purposes or warmer evenings. Heat-only mode is ideal for colder days when you need warmth without the visual of a flame. The combined mode gives you the best of both worlds. Consider how you intend to use the heater most often – if ambiance is a priority, flame-only mode is a must-have. If you need reliable heat in all conditions, the combined mode is your best bet.
Safety Features
Outdoor heaters involve an open flame or high heat, so safety is paramount. Ninja heaters are designed with safety in mind, featuring spark and ember-free operation, making them safe to use on various surfaces like grass, stone and wood. The weather-resistant construction allows for safe outdoor storage year-round. However, always ensure proper ventilation and follow the manufacturer’s instructions for safe operation and placement.
Other Features to Consider:
- Control Method: Dial controls offer simple, intuitive operation.
- Fuel Type: All Ninja Fireside360 heaters use propane.
- Portability: While not lightweight, these heaters are designed for semi-permanent placement.
- Aesthetic Design: Available in different finishes (Black, Cyberspace) to match your outdoor décor.
- Included Accessories: Ceramic rocks are included for an authentic fire pit look.
- Smokeless Operation: Eliminates the mess and odor associated with traditional wood-burning fire pits.
- Ease of Ignition: Simple turn-of-a-dial ignition eliminates the need for matches or lighters.
